Abstract
Apparatus especially useful for centering an electronic component on a surface for subsequent pickup and placement on a circuit board. The apparatus includes a pair of jaws which are driven in unison toward and away from each other by a lead screw or similar mechanism, each of the jaws having a part adapted to engage a respective side of a component to be positioned. The engagement part of each jaw is resiliently loaded such as by a spring or air cylinder and is in a normally outward position. The jaws are pre-aligned so that they drive in unison toward a predetermined center line. A component place between the jaws is contacted by the engagement parts of the jaws when the jaws move toward each other, and is moved into alignment on the center line. The jaws over-travel the aligned position against the spring pressure of the jaws, this spring pressure providing an intended over-travel force which prevents excessive force on the component by the engaged jaws. The over-travel also allows acceptance of a range of component sizes for the same jaw configuration.
